Problem Details:I found that all the thumbnails, ranked status and the grades of my maps are all messed up today.And what I can do is to click in "Edit" of every song and exit edit window without doing anything, then the information would be correct.But I have thousands of maps! I have to spend such a long time recovering the map information!?So, are there any other ways that I can try to fix this problem?

Other ways I have tried but found not useful:1. Delete data/bt/ , it's not useful because my bug is not only about thumbnails;2. Delete osu.db, it's not useful either...3. Press F5 to refresh all the beat maps, not useful...

Video or screenshot showing the problem:1. Wrong thumbnails, ranked status and the grades

2. After clicked on "Edit" and exit edit window, the thumbnails, ranked status and the grades were corrected.

Thanks for your reply!I have tried this way. But after refreshing the beatmap list, I found that I can only see about 20% of my maps. Being afraid of the data loss, I finally gave up this idea and recovered my osu!.db file to the former version.

Sort by Title and scroll all the way up, and all the way down and make sure their are no maps that are just " // " If there are, please delete it.

Also to be sure we aren't just being silly about most of your maps not showing up, make sure you haven't messed with this option.

A recompiled database should of fixed your issue with the thumbnails, not exactly sure why it didn't. Sometimes it rarely doesn't seem to work, and I don't think anyone ever really found a fix. All I can suggest is trying again at your own risk.
